LANTERN.

Specification of Letters Patent.

` Patented May 7, 1912.

To all whom it may concern.:

Be it known that we, WILLIAM S. HAMM, a resident of Hubbard Woods, county of Cook, and State of Illinois, and FRANK A. Sor-IUETZ, a resident of Chicago, county of Cook, and State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Lanterns, of which the following is a specication, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to lanterns specially adapted for the use of railway trainmen, its object being to improve the structure of the frame of the lantern and means for retaining the oil pot in place.

The invention consists of the device hereinafter described and which is illustrated in the accompanying drawings, in which- Figure 1 is a detail vert-ical section, partly in elevation, of the lantern; Fig. 2 is an inverted plan section on the line 2-2 of Fig. 1; Fig. 3 is a similar view showing a modified form of construction; Figs. 4, 5 and 6 are details showing a modified form of the pot-retaining mechanism; and Fig. 7 is a detail showing a modified form of construction for connecting the upright guard 1nembers of the frame to the lantern base.

The guard frame of the lantern may be shown as composed of iiat upright bars 10 united by wire rings 11, as in Figs. 1 and 2, or the uprights may themselves be wire, as shown at 12, Fig. 3. In either case, the vertical guard frame members are bowed inwardly, defining the bottom portion of the lantern and the top of its base. The flat guard ring 13 fits against the instanding knees 14 formed by the inward bowing of the uprights 10, 12, and is provided with lateral depending lugs 15, each provided with wings 16, 17 at its outer end which fold against the uprights 10, and are preferably secured to these uprights by the application of molten metal, as tin.

In the modification shown in Fig. 3, the guard ring 13 is provided with depending flanges 18, apertured to form seats for the knees of the upright 12 and to accommodate clips 19 which are looped around these uprights, extend through the apertures and have their ends secured to the inner faces of the flanges 1S, by the application of molten metal. A globe-retaining ring 20 is seated I upon and secured to the guard ring 13. The

oil pot 21 is seated within a cup .22 which is secured to the guard ring 13 by means of spring catches. To this end the ring 13 is provided with downwardly turned lugs 23 having their lower ends bent outwardly as shown at 24. The catches, as shown in Figs. 1 and 2, are leaf springs 25, secured at one end to the outer face of the cup 22 and eX- tending circumferentially thereon. These springs are bent-` to form two outstanding loops; the loop 26 adjacent the free lend of the spring is suiciently large to permit the uninterrupted passage of the lugs 23, the

loop 27 is smaller and engages the outturned end 24 of the guard ring lug. Adjacent walls of the two loops are inclined so that as the cup 22 is turned, the spring will ride over the lug 23. These spring catches, and the cooperating guard ring lugs may be as numerous as may be desired. Three sets are shown in the drawings.

In the construction illustrated in Fig. 3, but one leaf spring 25 is employed, each of the other two lugs 23 being engaged by a linger 28 secured at one end to the outer face of the cup 22, and extending circumfer entially thereon, its free end outstanding sufficiently to permit the passage of the body of the lug 23, but engaging its outstanding end 24. These lingers may, however, normally bear against the wall of the outer face of the cup and have their extreme ends inclined outwardly, as shown at 29, to permit the lugs 23 to enter under them and force the linger outwardly as the cup is turned.

In the construction illustrated in Figs. 4, 5 and 6, in lieu of the downwardly turned lugs 23, at the outer margin of the guard ring, lugs 30 are struck down from the body of the ring. The cup 22 is provided at its upper end with an outstanding iiange 31 which bears against the outer face of the guard ring 13, and is apertured to receive the lugs 30. Leaf springs 32 are secured to the under face of the flange 31 and have their outer ends inclined downwardly, as shown at 33, to permit them to ride over the lugs 30 as the cup is turned, the body portion of the spring being looped, as shown at 34, to receive the lug and frictionally hold the cup in place.

We claim as our invention 1. In a lantern, in combination, a guard ring having depending lugs With hookshaped ends, a cup Within the line of the lugs, leaf spring catches att-ached to the outer face of the cup and being looped'out- Ward to receive the lugs.

2. In a lantern, in combination, a guard ring having depending lugs with hookshaped ends, a cup Within the line of the lugs, leaf spring fingers attached to the outer face of the cup and being inclined out- Wardly to pass outside of the lugs as the cup is turned, one of such lugs being loopshaped to provide a shoulder for engaging the lug With which it cooperates.
